We used that very same collection company that was mentioned on this site.  Unfortunately, they gave up their efforts after a few phone calls.  Apparently going after these folks that owe a few hunderd or even a few thousand dollars is just not fiscally advantageous for them either :-(

I'm not sure if it would work - but if we were all willing to give up some of our time and effort to persue deadbeats for each other maybe ... I don't know???
